Kalanchoe ‘Queen’ plants are popular flowering houseplants, known for vibrant, long-lasting blooms and a wide array of colors. Their straightforward care makes them appealing.
Kalanchoe Queen Plant Care
Kalanchoe Queen plants thrive in bright, indirect light; a south or west-facing window is often ideal. Too much direct sun can scorch leaves, while insufficient light may cause legginess and loss of glossy green color. Rotate the pot occasionally for even light exposure.
Allow the soil to dry completely between waterings, then water deeply until it drains from the pot’s bottom. Kalanchoe Queen stores water in its fleshy leaves, making it susceptible to root rot if overwatered.
A well-draining potting mix, such as one for cacti or succulents, is essential for Kalanchoe Queen to prevent water pooling around roots. It prefers average room temperatures, generally above 50°F (10°C), and tolerates standard household humidity.
Kalanchoe Queen plants are not heavy feeders and do not require frequent fertilization. If fertilizing, use a balanced, water-soluble fertilizer diluted to half-strength once a month during spring and summer. This provides nutrients without overwhelming the plant.
Promoting Kalanchoe Queen Blooms
Kalanchoe Queen are “short-day plants,” requiring specific light conditions to initiate flower bud formation. To encourage reblooming, provide 14 to 16 hours of uninterrupted darkness daily for 6 to 8 weeks, by placing the plant in a dark closet or under a box.
During this dark period, the plant builds energy for blooming. Once flower buds appear, return the plant to its bright, indirect light location. Removing spent flowers (deadheading) encourages more blooms. After the blooming cycle, light pruning can help shape the plant for its next rest period.
Troubleshooting Kalanchoe Queen Issues
Wilting leaves or mushy stems often indicate overwatering and potential root rot. If these symptoms appear, allow the soil to dry thoroughly before the next watering, and ensure adequate drainage. Yellowing leaves can also signal overwatering, nutrient deficiencies, or insufficient light. Adjusting watering and light exposure can resolve these issues.
A lack of blooms stems from not providing the necessary short-day light cycle; re-establishing the darkness routine is essential. Common houseplant pests like aphids and mealybugs can affect Kalanchoe Queen. Inspect plants regularly and address infestations with insecticidal soap or other treatments.
Kalanchoe plants contain toxins, which can be harmful if ingested by pets or humans. Symptoms in pets can include vomiting, diarrhea, and in severe cases, cardiac issues. Keep Kalanchoe Queen plants out of reach of animals.
